Onboard Logic Unit (OLU) Digital Outputs, Detailed Information - GF54.21-S-0034A

Model 447 

with code JO2 (OLU pre-installation) 

with code JO3 (OLU Connect Unit) 

with code JO4 (OLU Compute Unit) 

with code JO5 (OLU with head unit integration) 

except code XM7 (MOPF II) 

Digital outputs OLU communication module 

The OLU communication module is equipped with the following digital outputs:

Cable-free: 

• Bluetooth® 5.0
• Wi-Fi 802.11ac (WLAN)
• LTE cat6 (eSIM/μSIM)

Cabled: 

• 4 x GPIO ("General Purpose Input/Output"): If a general contact pin is at an integrated circuit. Irrespective of whether, as an input or output contact, its behavior is freely determinable by means of logical programming. No purpose is specified for "GPIO" contacts. They are therefore unassigned as standard.
• 1 x USB 2.0 (optional)
• LIN
• 3 x High Speed CAN
• Audio output (speaker)

Digital outputs OLU central computer 

The OLU central computer has the following digital outputs:

Cable-free: 

• -

Cabled: 

• 16 x GPIO general purpose input/output
• 2 x 100Base-Tx (Fast Ethernet)
• 1 x 1000Base-T
• 2 x 100Base-T1 BroadR-Reach
• 2 x USB 2.0
• CAN
• LVDS (optional)

LTE (Long Term Evolution)

LVDS (Low voltage differential signal)

USB (Universal Serial Bus)

Internal OLU communication (OLU communication module and OLU central computer) 

Both the OLU communications module and OLU central computer units communicate with each other within the OLU via "Fast Ethernet" as per "1000Base-T1 BroadR-Reach".

Vehicles with code JO3 (OLU connect unit) are only equipped with the OLU communication module component.

Vehicles with code JO4 (OLU compute unit) or with code JO5 (OLU with head unit integration) are equipped with both components (OLU communication module and OLU central computer).
